An exact timing for when the Android Oreo update will land on each of these watches is unclear, as this is just confirmation from Google that the manufacturers are adding the new features to each watch.

Those features aren't groundbreaking - it's some improvements to the battery life and added customization options (such as being able to change the vibration levels), as well as support for extra languages.

Even more watches

We know for certain the Huawei Watch 2 has already begun receiving the update in some markets. Some of those who are getting the update outside of the US and UK are also finding that the upgrade is bricking the Android Pay feature.

A Reddit thread shows lots of users losing the feature, but Google says that Android Pay should never have been live for those outside of the US and UK. Whether Huawei will later push Android Pay to other markets in a future update remains to be seen.

The Android Oreo update has already been confirmed for the watches below, and is beginning to rollout to devices now too.
